string怎样转byte()
jmail.Attachment.BinaryData

dim   stream_o
set   stream_o=Server.CreateObject( "adodb.stream ")
stream_o.Type   =   2   '1:adTypeBinary   ;   2:adTypeText
stream_o.Open  
'stream_o.Write   s_data
stream_o.WriteText     Attachment.BinaryData
stream_o.SaveToFile   file_name   ,   2
stream_o.Close
set   stream_o=nothing


保存后的jpg图片能用acdc打开，但不用ie和photoshop打开，说不是jpg标志，为什么那？假如用stream_o.Write   怎么实现那？就是asp中，string怎样转byte()


谢谢！

Function BytesToBstr(strBody,CodeBase)
dim objStream
set objStream = Server.CreateObject( "Adodb.Stream ")
objStream.Type = 1
objStream.Mode =3
objStream.Open
objStream.Write strBody
objStream.Position = 0
objStream.Type = 2
objStream.Charset = CodeBase
BytesToBstr = objStream.ReadText
objStream.Close
set objStream = nothing
End Function

用功譬若掘井，与其多掘数井而皆不及泉，何若老守一井，力求及泉而用之不竭乎?

------解决方案--------------------
<%
String funcname= request.getParameter( "funcname ").trim();
byte[] tempbyte = funcname.getBytes( "ISO-8859-1 ");
//String f=null;
//f = new String(tempbyte, "gb2312 ");
